ABSTRACT:
Embodiments of an exhaust gas recirculation (EGR) device comprise a mixing pipe having an air inlet port and an outlet port disposed at opposite ends of the mixing pipe, and an exhaust inlet port disposed at a region of the mixing pipe between the air inlet port and the outlet port, wherein the exhaust inlet port is configured to deliver exhaust to be mixed with air inside the mixing pipe. The exhaust gas recirculation (EGR) device further comprises a nozzle disposed internally within a region of the mixing pipe between the exhaust inlet ring and the outlet port such that the diffuser nozzle defines an outer mixing channel in the spacing between the diffuser nozzle and the mixing pipe region.
